I'm not a Meridian expert by any means, but I have a close friend that operates one Part 91 for a doctor. Of course I talk to him a lot about it! He loves the way it flies, and it's a pretty simple plane to operate. He claims 240-250 knots (forget at what altitude, though).
The problem is that his airplane only has about 1650 pounds of useful load, and if you fill the tanks (170 gals), you only get about 4 hours of flying time with reserves. With the tanks full and 4 moderately sized guys onboard, he's already over gross. The doctor only flies around Texas, so it's a good airplane for him, but if you need longer legs and plan on filling the plane with folks - you might want to look somewhere else.
